Description
BACKGROUND OF THE INVENTION
The present invention relates to computing devices. More
particularly, the present invention provides a system including a
plurality of computer modules that can independently operate to
provide backup capability, dual processing, and the like. Merely by
way of example, the present invention is applied to a modular
computing environment for desk top computers, but it will be
recognized that the invention has a much wider range of
applicability. It can be applied to a server as well as other
portable or modular computing applications.
Many desktop or personal computers, which are commonly termed PCs,
have been around and used for over ten years. The PCs often come
with state-of-art microprocessors such as the Intel Pentium.TM.
microprocessor chips. They also include a hard or fixed disk drive
such as memory in the giga-bit range. Additionally, the PCs often
include a random access memory integrated circuit device such as a
dynamic random access memory device, which is commonly termed DRAM.
The DRAM devices now provide up to millions of memory cells (i.e.,
mega-bit) on a single slice of silicon. PCs also include a high
resolution display such as cathode ray tubes or CRTs. In most
cases, the CRTs are at least 15 inches or 17 inches or 20 inches in
diameter. High resolution flat panel displays are also used with
PCs.
Many external or peripheral devices can be used with the PCs. Among
others, these peripheral devices include mass storage devices such
as a Zip.TM. Drive product sold by Iomega Corporation of Utah.
Other storage devices include external hard drives, tape drives,
and others. Additional devices include communication devices such
as a modem, which can be used to link the PC to a wide area network
of computers such as the Internet. Furthermore, the PC can include
output devices such as a printer and other output means. Moreover,
the PC can include special audio output devices such as speakers
the like.
PCs also have easy to use keyboards, mouse input devices, and the
like. The keyboard is generally configured similar to a typewriter
format. The keyboard also has the length and width for easily
inputting information by way of keys to the computer. The mouse
also has a sufficient size and shape to easily move a curser on the
display from one location to another location.
Other types of computing devices include portable computing devices
such as "laptop" computers and the like. Although somewhat
successful, laptop computers have many limitations. These computing
devices have poor display technology. In fact, these devices often
have a smaller flat panel display that has poor viewing
characteristics. Additionally, these devices also have poor input
devices such as smaller keyboards and the like. Furthermore, these
devices have limited common platforms to transfer information to
and from these devices and other devices such as PCs.
Up to now, there has been little common ground between these
platforms including the PCs and laptops in terms of upgrading,
ease-of-use, cost, performance, and the like. Many differences
between these platforms, probably somewhat intentional, has
benefited computer manufacturers at the cost of consumers. A
drawback to having two separate computers is that the user must
often purchase both the desktop and laptop to have "total"
computing power, where the desktop serves as a "regular" computer
and the laptop serves as a "portable" computer. Purchasing both
computers is often costly and runs "thousands" of dollars. The user
also wastes a significant amount of time transferring software and
data between the two types of computers. For example, the user must
often couple the portable computer to a local area network (i.e.,
LAN), to a serial port with a modem and then manually transfer over
files and data between the desktop and the portable computer.
Alternatively, the user often must use floppy disks to "zip" up
files and programs that exceed the storage capacity of conventional
floppy disks, and transfer the floppy disk data manually.
Another drawback with the current model of separate portable and
desktop computer is that the user has to spend money to buy
components and peripherals the are duplicated in at least one of
these computers. For example, both the desktop and portable
computers typically include hard disk drives, floppy drives,
CD-ROMs, computer memory, host processors, graphics accelerators,
and the like. Because program software and supporting programs
generally must be installed upon both hard drives in order for the
user to operate programs on the road and in the office, hard disk
space is often wasted.
One approach to reduce some of these drawbacks has been the use of
a docking station with a portable computer. Here, the user has the
portable computer for "on the road" use and a docking station that
houses the portable computer for office use.
Similar to separate desktop and portable computers, there is no
commonality between two desktop computers. To date, most personal
computers are constructed with a single motherboard that provides
connection for CPU and other components in the computer. Dual CPU
systems have been available through Intel's slot 1 architecture.
For example, two Pentium II cartridges can be plugged into two
"slot 1" card slots on a motherboard to form a Dual-processor
system. The two CPU's share a common host bus that connects to the
rest of the system, e.g. main memory, hard disk drive, graphics
subsystem, and others. Dual CPU systems have the advantage of
increased CPU performance for the whole system. Adding a CPU
cartridge requires no change in operating systems and application
software. However, dual CPU systems may suffer limited performance
improvement if memory or disk drive bandwidth becomes the limiting
factor. Also, dual CPU systems have to time-share the processing
unit in running multiple applications. CPU performance improvement
efficiency also depends on software coding structure. Dual CPU
systems provide no hardware redundancy to help fault tolerance. In
running multiple applications, memory and disk drive data
throughput will become the limiting factor in improving performance
with multi-processor systems.
Thus, what is needed are computer systems that can have multiple
computer modules. Each computer module has dedicated memory and
disk drive, and can operate independently.
SUMMARY OF THE INVENTION
According to the present invention, a technique including a method
and device for multi-module computing is provided. In an exemplary
embodiment, the present invention provides a system including a
plurality of computer modules that can independently operate to
provide backup capability, dual processing, and the like.
In a specific embodiment, the present invention provides a computer
system for multi-processing purposes. The computer system has a
console comprising a first coupling site and a second coupling
site, e.g., computer module bay. Each coupling site comprises a
connector. The console is an enclosure that is capable of housing
each coupling site. The system also has a plurality of computer
modules, where each of the computer modules is coupled to one of
the connectors. Each of the computer modules has a processing unit,
a main memory coupled to the processing unit, a graphics controller
coupled to the processing unit, and a mass storage device coupled
to the processing unit. Each of the computer modules is
substantially similar in design to each other to provide
independent processing of each of the computer modules in the
computer system.
In an alternative specific embodiment, the present invention
provides a multi-processing computer system. The system has a
console comprising a first coupling site and a second coupling
site. Each coupling site comprises a connector. The console is an
enclosure that is capable of housing each coupling site. The system

computer modules is coupled to one of the connectors. Each of the
computer modules has a processing unit, a main memory coupled to
the processing unit, a graphics controller coupled to the
processing unit, a mass storage device coupled to the processing
unit, and a video output coupled to the processing unit. Each of
the computer modules is substantially similar in design to each
other to provide independent processing of each of the computer
modules in the computer system. A video switch circuit is coupled
to each of the computer modules through the video output. The video
switch is configured to switch a video signal from any one of the
computer modules to a display.
Numerous benefits are achieved using the present invention over
previously existing techniques. In one embodiment, the invention
provides improved processing and maintenance features. The
invention can also provide increased CPU performance for the whole
system. The invention also can be implemented without changes in
operating system and application software. The present invention is
also implemented using conventional technologies that can be
provided in the present computer system in an easy and efficient
manner.
In another embodiment, the invention provides at least two users to
share the same modular desktop system. Each user operates on a
different computer module. The other peripheral devices, i.e.
CDROM, printer, DSL connection, etc. can be shared. This provides
lower system cost, less desktop space and more efficiency.
Depending upon the embodiment, one or more of these benefits can be
available. These and other advantages or benefits are described
throughout the present specification and are described more
particularly below.

DESCRIPTION OF SPECIFIC EMBODIMENTS
According to the present invention, a technique including a method
and device for multi-module computing is provided. In an exemplary
embodiment, the present invention provides a system including a
plurality of computer modules that can independently operate to
provide backup capability, dual processing, and the like.
FIG. 1 is a simplified diagram of a computer system 100 according
to an embodiment of the present invention. This diagram is merely
an illustration and should not limit the scope of the claims
herein. One of ordinary skill in the art would recognize other
variations, modifications, and alternatives. The computer system
100 includes an attached computer module (i.e., ACM) 113, a desktop
console 101, among other elements. The computer system also has
another ACM module 117. Each ACM module has a respective slot 121,
119, which mechanically houses and electrically couples each ACM to
the computer console. Also shown is a display 111, which connects
to the console. Additionally, keyboard 109 and mouse 115 are also
shown. A second display 102, keyboard 105, and mouse 107 can be
coupled to the console in some optional embodiments to allow more
than one user to operate the computer system. The computer system
is modular and has a variety of components that are removable. Some
of these components (or modules) can be used in different
computers, workstations, computerized television sets, and portable
or laptop units.
In the present embodiment, each ACM 113 includes computer
components, as will be described below, including a central
processing unit ("CPU"), IDE controller, hard disk drive, computer
memory, and the like. The computer module bay (i.e., CMB) 121 is an
opening or slot in the desktop console. The CMB houses the ACM and
provides communication to and from the ACM. The CMB also provides
mechanical protection and support to the ACM. The CMB has a
mechanical alignment mechanism for mating a portion of the ACM to
the console. The CMB further has thermal heat dissipation sinks,
electrical connection mechanisms, and the like. Some details of the
ACM can be found in co-pending Patent Application Nos. 09/149,882
and 09/149,548 filed Sep. 8, 1998, commonly assigned, and hereby
incorporated by reference for all purposes.
In a specific embodiment, the present multiple computer module
system has a peripheral console that has two or more computer bays
that can receive a removable computer module or ACM. Multiple
computer module system can function as a personal computer with
only one ACM and the peripheral console. The second and additional
ACM can be added later to increase overall system performance and
reliability. The ACM operates independently as self-contained
computer, communicates with each other through a high-speed serial
communication and share most peripheral devices within the
peripheral console. Each ACM controls its independent graphics
subsystem and drives separate video output signals. A practical
implementation is a dual ACM system. In a dual ACM system, two
monitors can be used to display the two ACMs' graphics outputs at
the same time. For a single monitor, a RGB switch is used to switch
between the video outputs of the two ACMs and can be controlled by
a command from the user. Similarly, input devices (i.e. keyboard
and mouse) are switched between the two computer systems with a
command from the user. Command from the user can be in the form of
either a dedicated key on the keyboard or a special icon on the
screen that the mouse can click on.
In most embodiments, the ACM includes an enclosure such as the one
described with the following components, which should not be
limiting: 1) A CPU with cache memory; 2) Core logic device or
means; 3) Main memory; 4) A single primary Hard Disk Drive ("HDD")
that has a security program; 5) Flash memory with system BIOS and
programmable user password; 6) Operating System, application
software, data files on primary HDD; 7) An interface device and
connectors to peripheral console; 8) A software controllable
mechanical lock, lock control means, and other accessories.
The ACM connects to a peripheral console with power supply, a
display device, an input device, and other elements. Some details
of these elements with the present system are described in more
detail below. In a dual ACM system, the primary ACM can connect
directly to the peripheral board in the peripheral console. The
second ACM can connect either directly or indirectly to the
peripheral board. For indirect connection, a receptacle board is
added to allow a cable connection to the peripheral board. This is
to facilitate the mechanical positioning of the second ACM inside
the computer chassis. The receptacle board approach can even be
used for the primary ACM if a high bandwidth peripheral bus, e.g.
PCI Bus, is not connected from the primary ACM to the peripheral
board.
The shared peripheral console has a chassis and a motherboard that
connects the following devices:
1) Input means, e.g. keyboard and mouse,
2) Display means, e.g. RGB monitor,
3) Add-on means, e.g. PCI add-on slots,
4) Two Computer Module Bays (CMB) with connectors to two ACMs,
5) A serial communication Hub controller that interfaces to serial
communication controller of both ACMs,
6) Shared storage subsystem, e.g. Floppy drive, CDROM drive, DVD
drive, or 2nd Hard Drive,
7) Communication device, e.g. modem,
8) Power supply, and others.
The computer bay is an opening in the peripheral console that
receives an ACM. CMB provides mechanical protection to ACM,
mechanical alignment for connector mating, mechanical locking
system to prevent theft and accidental removal, and connectors at
the end of the opening for connecting to ACM. The interface bus
between ACM and the peripheral console has a video bus, peripheral
connections, serial communication connection, control signals and
power connection. Video bus includes video output of graphics
devices, i.e. analog RGB and control signals for monitor. Power
connection supplies the power for ACM.
An implementation of peripheral sharing is the use of Ethernet
controllers to bridge the communication between the two ACMs. Some
of the peripheral devices residing in the peripheral console are
shown in the simplified diagram of FIG. 2. As shown, the diagram is
merely an illustration which should not limit the scope of the
claims herein. One of ordinary skill in the art would recognize
many other variations, alternatives, and modifications. As shown, a
primary ACM 203 is connected to PCI peripheral devices in the
peripheral console through the PCI bus 225 that passes through the
connection between primary ACM 203 and peripheral console 201. As
shown, ACM has a CPU module 207 coupled to the PCI bus through a
North Bridge 211.
The CPU module can use a suitable microprocessing unit,
microcontroller, digital signal processor, and the like. In a
specific embodiment, the CPU module uses, for example, a 400 MHz
Pentium II microprocessor module from Intel Corporation and like
microprocessors from AMD Corporation, Cyrix Corporation (now
National Semiconductor Corporation), and others. In other aspects,
the microprocessor can be one such as the Compaq Computer
Corporation Alpha Chip, Apple Computer Corporation PowerPC G3
processor, and the like. Further, higher speed processors are
contemplated in other embodiments as technology increases in the
future.
In the CPU module, peripheral controller 213 is coupled to
BIOS/flash memory 217. Additionally, the peripheral controller is
coupled to a clock control logic, a configuration signal, and a
peripheral bus. The ACM has the hard drive module 215. Among other
elements, the ACM includes north bridge 215, graphics subsystem 223
(e.g., graphics accelerator, graphics memory), an IDE controller,
and other components. Adjacent to and in parallel alignment with
the hard drive module 215 is the PCI bus. In a specific embodiment,
North Bridge unit 211 often couples to a computer memory 209, to
the graphics subsystem, and to the peripheral controller via the
PCI bus. Graphics subsystem typically couples to a graphics memory,
and other elements. IDE controller generally supports and provides
timing signals necessary for the IDE bus. In the present
embodiment, the IDE controller is embodied as part of a P114XE
controller from Intel, for example. Other types of buses than IDE
are contemplated, for example EIDE, SCSI, 1394, and the like in
alternative embodiments of the present invention.
The hard drive module or mass storage unit 215 typically includes a
computer operating system, application software program files, data
files, and the like. In a specific embodiment, the computer
operating system may be the Windows98 operating system from
Microsoft Corporation of Redmond Washington. Other operating
systems, such as Windows.sup.NT, MacOS8, Unix, and the like are
also contemplated in alternative embodiments of the present
invention. Further, some typical application software programs can
include Office98 by Microsoft Corporation, Corel Perfect Suite by
Corel, and others. Hard disk module 215 includes a hard disk drive.
The hard disk drive, however, can also be replaced by removable
hard disk drives, read/write CD ROMs, flash memory, floppy disk
drives, and the like. A small form factor, for example 2.5'', is
currently contemplated, however, other form factors, such as PC
card, and the like are also contemplated. Mass storage unit 240 may
also support other interfaces than IDE. Among other features, the
computer system includes an ACM with security protection.
The ACM also has a network controller, which can be an Ethernet
controller 219, which is coupled to the North Bridge through the
PCI bus. The North Bridge is coupled to the CPU. The Ethernet
controller can be a 10/100 Base, such as Intel's 82559 or the like.
Other types of network connection devices can also be used. For
example, the invention can use Gbit Ethernet 1394, and USB 2.0. The
network controller couples to a hub 233 in the console, which
includes shared peripheral system 201.
Also shown is the second ACM 205. The second ACM has the same or
similar components as the first ACM. Here, like reference numerals
have been used for easy cross-referencing, but is not intended to
be limiting. In some embodiments, the secondary ACM is not
connected to the PCI bus in the peripheral console directly. The
secondary ACM 219 accesses peripheral devices controlled by the
primary ACM through the Ethernet connection to the primary ACM,
e.g. CD-ROM, or PCI modem. The implementation is not restricted to
Ethernet serial communication and can use other high-speed serial
communication such as USB 2.0, and 1394. The Ethernet hub is
coupled to an external output port 235, which connects to an
external network.
The primary hard disk drive in each ACM can be accessed by the
other ACM as sharable hard drive through the Ethernet connection.
This allows the easy sharing of files between the two independent
computer modules. The Ethernet Hub Controller provides the
high-speed communication function between the two computer modules.
Ethernet data bandwidth of 100 Mbit/sec allows fast data
communication between the two computer modules. The secondary ACM
access peripheral devices of the primary ACM through the network
connection provided by Ethernet link. The operating system, e.g.
Windows 98, provides the sharing of resources between the two ACMs.
In some embodiments, critical data in one ACM can be backup into
the other ACM.
The Ethernet hub also couples to PCI bus 239, which connects to PCI
devices 241, 243, e.g., modem, SCSI controller. A flash memory 242
can also be coupled to the PCI bus. The flash memory can store
passwords and security information, such as those implementations
described in U.S. Ser. No. 09/183,493, which is commonly owned, and
hereby incorporated by reference. The hub 233 also couples to an
I/O control 237, which connects to keyboard/mouse switch 245, which
couples to keyboard/mouse 247. Optionally, the keyboard/mouse
switch also couples to a second keyboard/mouse 259 via PS2 or USB
signal line 251. The keyboard/mouse switch has at least a first
state and a second state, which allow operation of respectively
multiple keyboards or a single keyboard. The switch also couples to
each I/O controller 221 in each ACM via lines 253, 255. The I/O
control 237 also couples to an RGB switch 257, which allows video
signals to pass to the first monitor 259. Alternatively, the RGB
switch couples to a second monitor 261. The RGB switch includes
analog video switches such as MAXIM's MAX4545.
The peripheral system 201 also has an independent power supply 231
for each ACM. Each power supply provides power to each ACM. As
merely an example, the power supply is a MICRO ATX 150W made by
ENLIGHT, but can be others. The power supply is connected or
coupled to each ACM through a separate line, for example. The
independent power supply allows for independent operation of each
ACM in some embodiments.
The above embodiments are described generally in terms of hardware
and software. It will be recognized, however, that the
functionality of the hardware can be further combined or even
separated. The functionality of the software can also be further
combined or even separated. Hardware can be replaced, at times,
with software. Software can be replaced, at times, with hardware.
Accordingly, the present embodiments should not be construed as
limiting the scope of the claims here. One of ordinary skill in the
art would recognize other variations, modifications, and
alternatives.

according to an alternative embodiment of the present invention.
This diagram is merely an example which should not limit the scope
of the claims herein. One of ordinary skill in the art would
recognizes many other variations, modifications, and alternatives.
Like reference numerals are used in this Fig. as the previous Figs.
for easy referencing, but are not intended to be limiting. As
shown, each ACM includes common elements as the previous Fig. A
primary ACM 203 is connected to PCI peripheral devices in the
peripheral console through the PCI bus 225 that passes through the
connection between primary ACM 203 and peripheral console 201. As
shown, ACM has a CPU module 207 coupled to the PCI bus through a
North Bridge 211.
The CPU module can use a suitable microprocessing unit,
microcontroller, digital signal processor, and the like. In a

files, and the like. In a specific embodiment, the computer
operating system may be the Windows98 operating system from
Microsoft Corporation of Redmond Wash. Other operating systems,
such as Windows.sup.NT, MacOS8, Unix, and the like are also

Further, some typical application software programs can include
Office98 by Microsoft Corporation, Corel Perfect Suite by Corel,
and others. Hard disk module 215 includes a hard disk drive. The
hard disk drive, however, can also be replaced by removable hard

contemplated, however, other form factors, such as PC card, and the
like are also contemplated. Mass storage unit 240 may also support
other interfaces than IDE. Among other features, the computer
system includes an ACM with security protection.
The ACM also has a network controller, which can be coupled to a
serial port 302, which is coupled to the PCI bus in the ACM. The
serial port is coupled to the peripheral console through a serial
controller 301 in the serial console. The serial controller is
connected to PCI bus 239. The serial controller is also coupled to
a serial hub controller 303, which is coupled to the PCI bus and a
second ACM. In a specific embodiment, a receptacle board 310 is
added to connect to the second ACM. The purpose of the receptacle
board is to allow a cable connection 307 to the peripheral board
300. The cable connection is possible because the signals needed to
connect to the peripheral board can be limited to video, I/O,
serial communication, and power. The serial communication
controller can be placed on the receptacle board and not in the
ACM. As shown, the serial bus controller couples to the PCI bus.
The receptacle board also couples to power, graphics subsystem, I/O
controller, and other elements, which may be on a common bus. The
overall operation of the present configuration is similar to the
previous one except it operates in serial communication mode.
The Dual ACM system can support different usage models:
1. One user using both ACMs concurrently with 1 or 2 monitors, and
a common keyboard/mouse.
2. Two users using the two separate ACMs at the same time with
separate monitors and keyboard/mouse. The 2 users share
peripherals, e.g., printer, CDROM, and others. The two users share
external networking.
To support 1 monitor for both ACMs, a video switch in the
peripheral console is used to switch between the video outputs of
the two ACMs. The system can be set to support either 1 monitor or
2-monitor mode. The user presses a special key on the keyboard or a
special icon on the screen to switch the screen display from one
ACM to the other. This same action causes the keyboard and mouse
connections to switch from one ACM to the other ACM.
A dual ACM system can save space, wiring, and cost for a 2-person
PC setup, with the added benefit that both PC systems can be
accessed from one user site for increased system performance if the
other user is not using the system. Files can be copied between the
primary drive of both system and provides protection against a
single ACM failure. Software needs to be developed to manage the
concurrent use of two PC subsystems, the automatic sharing of
selected files between the two systems, and fault tolerance.
The design with more than two computer modules can be implemented
with the use of multi-port, serial communication hub controller and
multi-port I/O switches. In one embodiment, a peripheral console
has four computer bays for four separate computer modules. The
computer modules communicate through a four port Ethernet hub. The
video, keyboard, and mouse switch will cycle through the connection
from each computer module to the external monitor, keyboard, and
mouse with a push button sequentially. This embodiment is useful
for a server that performs different functions concurrently, e.g.
email, application hosting, web hosting, firewall, etc.
The above embodiments are described generally in terms of hardware
and software. It will be recognized, however, that the
functionality of the hardware can be further combined or even
separated. The functionality of the software can also be further
combined or even separated. Hardware can be replaced, at times,
with software. Software can be replaced, at times, with hardware.
Accordingly, the present embodiments should not be construed as
limiting the scope of the claims here. One of ordinary skill in the
art would recognize other variations, modifications, and
alternatives.
FIG. 4 is a simplified diagram of a method according to an
embodiment of the present invention. This diagram is merely an
example which should not limit the scope of the claims herein. One
of ordinary skill in the art would recognize many other variations,
modifications, and alternatives. The present diagram illustrates an
automatic file backup procedure from one computer module to the
other. As shown, a user selects (step 401) a certain file in one of
the computer module for automatic backup. Next, the method
determines if another module is available, step 403. If so, the
method in the originating module requests the other computer module
to create (step 405) backup file. Alternatively, the method alerts
the user of the missing or malfunctioning module, step 429. The
method then has the user try later 431, once the missing or
malfunctioning module has been replaced or repaired. Next, the
method determines if there is sufficient storage available in the
other computer module for the backup files. If so, the method goes
to the next step. (Alternatively, the method prompts (step 433) a
message to the user indicating that the storage is full.) In the
next step, the method stores the backup file in memory of the other
module. After the backup file has been successfully created (step
409), the software in the originating ACM sets a timer to check
(step 411) for file modification via branches 423, 427 through
continue, step 425 process. If a file selected for backup has been
modified (step 415), then the file is automatically back up to the
other ACM again, step 417. Alternatively, the method returns to
step 411 through branch 421.
The above embodiments are described generally in terms of hardware
and software. It will be recognized, however, that the
functionality of the hardware can be further combined or even
separated. The functionality of the software can also be further
combined or even separated. Hardware can be replaced, at times,
with software. Software can be replaced, at times, with hardware.
Accordingly, the present embodiments should not be construed as
limiting the scope of the claims here. One of ordinary skill in the
art would recognize other variations, modifications, and
alternatives.
While the above is a full description of the specific embodiments,
various modifications, alternative constructions and equivalents
may be used. Therefore, the above description and illustrations
should not be taken as limiting the scope of the present invention
which is defined by the appended claims.
